Greetings, I would appreciate any information that will help me restore two 180 GB ATA drives to full capacity from the 28 GB "availabiile" that is now reflected for each drive. I installed a new 750 GB hard drive in the front tray of my 1.42 GH mirrored door G4 and made it my system drive. Now the two 180 GB drives in the rear tray (one of which was previously the system drive), show in "Get Info" that only 28 GB are available in each of the drives. Both 180 GB drives came in the computer when it was new. Floy
